Silica dust and our powder duster make the perfect combination to combat a number of pesty issues! This set includes 1lb of white nonindicating Silica dust (similar to a powder) and our high quality metal powder duster. The Silica dust is often used with a pesticide powder duster to help fight against pests (bed bugs, horse flys, bees, etc.). Our powder duster enables you to precisely apply the Silica dust into cracks and crevices, wall voids, and other hardtoreach areas. Simply fill the powder duster half full with the appropriate dust or bait and replace the lid and you are good to go!
